Summer Job Money Guide for Teenagers

A teen working 20 hours a week at $15 an hour for ten summer weeks earns $3,000. Put even part of that into a Roth IRA at 16 and it can grow to tens of thousands of dollars by age 60. The summer job is the highest-leverage money event in a teenager's life, and most teens spend the whole thing by October.

The first real paycheck also comes with invisible complications: taxes withheld that nobody expected, a W-4 form nobody explained, and a strong pull to spend the whole summer's work on the summer itself.

This guide covers what a summer paycheck actually looks like after taxes, how the W-4 works for a minor, the simple 3-way split that makes the money last, and why a Roth IRA is the single best use of summer earnings.

What the Paycheck Actually Looks Like

The withholding surprise

Every paycheck has FICA taken off the top: 7.65% for Social Security and Medicare, for everyone, no exceptions. State tax may take a bit more depending on where you live.

Federal income tax is a different story. Most teens owe nothing on summer-only income, because the 2026 standard deduction is $16,100 and a typical summer earns far less than that. But money still gets withheld from every check unless the W-4 says otherwise. Our post on what a W-4 form is walks through filling it out.

The W-4 for a teen

If your total income for the year will be under the standard deduction, you can write "Exempt" on the W-4 and stop federal income tax withholding entirely. The paycheck gets bigger immediately.

If you are not exempt, file a return in the spring anyway. Most teens get every withheld dollar back as a refund. The IRS has a free tool that checks whether you need to file. Our guides on filing taxes as a teenager and reading your first W-2 cover the spring side.

Self-employment is different

Lifeguarding for a camp is a W-2 job. Mowing lawns for neighbors is self-employment, and the rules change. Net self-employment income over $400 for the year triggers self-employment tax of about 15.3%, and you file a return for it. Track your income and expenses (gas, equipment, supplies) from day one, because expenses reduce what you owe. Our post on self-employment taxes for teenagers has the full breakdown.

One more thing for younger teens: federal rules limit the hours and jobs 14 and 15 year olds can work, while 16 and 17 year olds can work unlimited hours in non-hazardous jobs. State rules can be stricter.

The 3-Way Split

Spend, save, invest

A durable default for a summer paycheck: 50% for spending (it is your money and summer is short), 30% for near-term savings (car costs, college expenses, senior year), and 20% invested for the long term.

Adjust the percentages to fit your life. The structure is the point. A teen who learns that money gets allocated before it gets spent has learned the adult skill early. Our post on how much a teenager should save helps pick the numbers, and checking versus savings accounts for teens covers where the money lives.

The Roth IRA pitch, with math

Any teen with earned income can contribute to a custodial Roth IRA, up to what they earned or $7,500 for 2026, whichever is less. A parent opens and manages the account; the contributions grow tax-free for 50 years or more.

The math that lands: $1,000 invested at 16 grows to roughly $29,000 by age 66 at a 7% average return. Parents can even contribute or match on the teen's behalf, as long as the teen had real earnings to cover the contribution. Read our posts on Roth IRAs for teens, custodial accounts, and how compound interest works for the setup details.

The car-fund trap

A $4,000 car bought with the whole summer's pay is the classic trap. The car costs insurance (often $200 or more a month for a teen driver), gas, and maintenance on top of the purchase price. Add up the annual total before the keys change hands. When you are ready, our guide on car loans without getting ripped off is worth a read.

Real-World Examples

Example: The lifeguard, 16

Situation: Earned $3,200 over ten weeks at a camp job.

What she did: Wrote "Exempt" on the W-4 so her checks skipped federal withholding. Split the money three ways: $1,600 for summer spending, $1,000 toward senior-year car insurance, $600 into a custodial Roth her dad matched dollar-for-dollar.

Result: $1,200 went into the Roth at age 16, which projects to roughly $35,000 by age 66. Exempt status plus the parent match turned one summer into retirement seed money.

Example: The lawn-mowing entrepreneur, 17

Situation: Earned $2,600 mowing lawns with no employer and no W-2.

What he did: Logged $400 of fuel and equipment expenses, learned he owed self-employment tax on the $2,200 net (about $337), and filed a simple return instead of ignoring it.

Result: Still put $500 into a Roth. Side money is real income with real taxes, and filing is part of the job.

Example: The second-summer reset, 15

Situation: Earned $1,900 his first summer and spent all of it by September on fast food and games.

What he did: Before the first paycheck of year two, his parents set the split in writing: 50% spending, 30% savings, 20% investing, with a capped spending account.

Result: Same earnings, but year two ended with $570 saved and $380 invested. The split has to exist before the money does.

Common Mistakes

• Spending the gross. FICA and withholding shrink the check before it arrives. Budget on what lands in the account, not the hourly rate times hours.
• Skipping the W-4 exempt line. Teens earning under the standard deduction who do not claim exempt give the IRS an interest-free loan until next spring's refund.
• Ignoring self-employment tax. Mowing lawns, babysitting, or reselling for more than $400 of net profit is taxable income with its own tax rate.
• Letting the whole summer fund the summer. The first earned dollars are the highest-compounding dollars of a lifetime. Even 20% invested beats everything a 40-year-old can do with the same money.
• Parents keeping the refund. A withholding refund belongs to the kid who earned it. Returning it is part of teaching the system.

Conclusion

A summer job is a finance course disguised as a paycheck. Handle the W-4 correctly so you are not lending the government money, run the 3-way split so the money has a job before it has a spending plan, and put something in a Roth IRA before the first check evaporates. Summer money compounds longer than any other money you will ever touch.

Before the first paycheck, sit down together and write the split on paper: spend, save, invest. Then read our teen Roth IRA guide and open the account the same week. The BLS youth employment data says roughly a third of teens work each summer; the ones with a plan keep far more of it.
